de6cd7599b meson: Replace softmmu_ss -> system_ss
We use the user_ss[] array to hold the user emulation sources,
and the softmmu_ss[] array to hold the system emulation ones.
Hold the latter in the 'system_ss[]' array for parity with user
emulation.

Mechanical change doing:

  $ sed -i -e s/softmmu_ss/system_ss/g $(git grep -l softmmu_ss)

2019cabfee meson: subprojects: replace submodules with wrap files
Compared to submodules, .wrap files have several advantages:

* option parsing and downloading is delegated to meson

* the commit is stored in a text file instead of a magic entry in the
  git tree object

* we could stop shipping external dependencies that are only used as a
  fallback, but not break compilation on platforms that lack them.
  For example it may make sense to download dtc at build time, controlled
  by --enable-download, even when building from a tarball.  Right now,
  this patch does the opposite: make-release treats dtc like libvfio-user
  (which is not stable API and therefore hasn't found its way into any
  distros) and keycodemap (which is a copylib, for better or worse).

dependency() can fall back to a wrap automatically.  However, this
is only possible for libraries that come with a .pc file, and this
is not very common for libfdt even though the upstream project in
principle provides it; it also removes the control that we provide with
--enable-fdt={system,internal}.  Therefore, the logic to pick system
vs. internal libfdt is left untouched.

--enable-fdt=git is removed; it was already a synonym for
--enable-fdt=internal.

ac4ccac740 configure: rename --enable-pypi to --enable-download, control subprojects too
The behavior of --{enable,disable}-pypi is similar to that of
-Dwrapmode={default,nodownload} respectively.  In particular,
in both cases a feature needs to be explicitly enabled for the
dependency to be downloaded.

So, use a single option to control both cases.  Now, --enable-slirp
will trigger cloning and building of libslirp if the .pc file
is not found on the machine.

50cfed80ec configure: remove --with-git= option
The scenario for which --with-git= was introduced was to use a SOCKS proxy
such as tsocks.  However, this was back in 2017 when QEMU's submodules
used the git:// protocol, and it is not as important when using the
"smart HTTP" backend; for example, neither "meson subprojects download"
nor scripts/checkpatch.pl obey the GIT environment variable.

So remove the knob, but test for the presence of git in the configure and
git-submodule.sh scripts, and suggest using --with-git-submodules=validate
+ a manual invocation of git-submodule.sh when git does not work.  Hopefully
in the future the GIT environment variable will be supported by Meson.

Commit 1b0578f5c4 ("qemu-pr-helper: Fix build on CentOS 7") added

merge commit 8c345b3e6a (June 2021) we don't build/test CentOS 7 as
it felt out of our list of supported distrib versions. Therefore we
can safely remove the 'old' API check (mostly reverting commit
1b0578f5c4, except the code got converted to meson in commit
6ec0e15d95 "meson: move libmpathpersist test").

6da5f22b65 meson.build: Use -Wno-undef only for SDL2 versions that need it
There is no need to disable this useful compiler warning for
all versions of the SDL. Unfortunately, various versions are
buggy (beside SDL 2.0.8, the version 2.26.0 and 2.26.1 are
broken, too, see https://github.com/libsdl-org/SDL/issues/6619 ),
but we can use a simple compiler check to see whether we need
the -Wno-undef or not.

This also enables the printing of the version number with
good versions of the SDL in the summary of the meson output
again.

09a49afeae meson: Avoid implicit declaration of absent functions
While detecting a presence of a function via 'cc.links()'
gives desired result (i.e. detects whether function is present),
it also produces a warning on systems where the function is not
present (into meson-log.txt), e.g.:

  qemu.git/build/meson-private/tmph74x3p38/testfile.c:2:34: \
  warning: implicit declaration of function 'malloc_trim' [-Wimplicit-function-declaration]

And some distributions (e.g. Gentoo) parse the meson log and
consider these erroneous because it can lead to feature
misdetection (see [1]).

We can check whether given function exists via
'cc.has_function()' or whether STATX_* macros exist via
'cc.has_header_symbol()'.

98b126f5e3 qapi: add '@fdset' feature for BlockdevOptionsVirtioBlkVhostVdpa
The virtio-blk-vhost-vdpa driver in libblkio 1.3.0 supports the fd
passing through the new 'fd' property.

Since now we are using qemu_open() on '@path' if the virtio-blk driver
supports the fd passing, let's announce it.
In this way, the management layer can pass the file descriptor of an
already opened vhost-vdpa character device. This is useful especially
when the device can only be accessed with certain privileges.

Add the '@fdset' feature only when the virtio-blk-vhost-vdpa driver
in libblkio supports it.

data movement works, and it can be used for atomic128.

b03fcd6818 meson: move -no-pie from linker to compiler
The large comment in the patch says it all; the -no-pie flag is broken and
this is why it was not included in QEMU_LDFLAGS before commit a988b4c561
("build: move remaining compiler flag tests to meson", 2023-05-18).  And
some distros made things even worse, so we have to add it to the compiler
command line.

We want to only enable '-Wno-unused-function' if glib's version is
smaller than '2.57.2' and has a G_DEFINE_AUTOPTR_CLEANUP_FUNC()
implementation that doesn't take into account unused functions. But the
compilation test isn't working as intended as '-Wunused-function' isn't
enabled while running it.

Let's enable it.

95caf1fb42 build: move warning flag selection to meson
Meson already knows to test with the positive form of the flag, which
simplifies the test.  Warnings are now tested explicitly for the C++
compiler, instead of hardcoding those that are only available for
the C language.

At this point all compiler flags in QEMU_CFLAGS are global and only
depend on the OS.  No feature tests are performed in configure.

d67212d47f meson: prepare move of QEMU_CFLAGS to meson
Clean up the handling of compiler flags in meson.build, splitting
the general flags that should be included in subprojects as well,
from warning flags that only apply to QEMU itself.  The two were
mixed in both configure tests and meson tests.

This split makes it easier to move the compiler tests piecewise
from configure to Meson.

fc9a809e0d build: move glib detection and workarounds to meson
QEMU adds the path to glib.h to all compilation commands.  This is simpler
due to the pervasive use of static_library, and was grandfathered in from
the previous Make-based build system.  Until Meson 0.63 the only way to
do this was to detect glib in configure and use add_project_arguments,
but now it is possible to use add_project_dependencies instead.

gmodule is detected in a separate variable, with export enabled for
modules and disabled for plugin.
